Reminders is a task management program developed by Apple Inc. for their iOS, macOS and watchOS platforms that allows users to create lists and set notifications for themselves.

[2] Reminders are placed into four categories which can be found at the top of the screen; "Today", "Scheduled", "All", and "Flagged".

Tasks appear in the Notification Center 24 hours before the time a reminder is set for.

[6] Lists can be synced between iOS and macOS through iCloud[7] as well as shared with other contacts.

Once shared, tasks can be added or completed by anyone with access to a list and specific reminders can be assigned to different people.
